To all whom, it may concern.-

Be it known that I, SAMUEL MoRsoN CUN- NINGHAM, a citizen of the United States, residing in Coyote, in the county of Santa Clara and State of California, have invented a new and useful Side-Hill Gang-Plow, of which the following is a specification.

My invention relates to improvements in side-hill plows, which will be readily under- O, D, and D, E and E, F F and F F form the frame of the machine, being joined to the plow-beam and axle; G and G, the seat sup ports; H, the seat-springs; I, the seat; J, the axle; .i and K, the adjusting guide-wheels.

L and L are the raising-levers for the adjusting guide-wheels; M and M, the catchlevers for the adjustment of the levers L and L, by means of the springs N and N; L and L, the raising-levers for the plows; M and M the catch-levers for adjusting the levers L and L, and N and N the springs for the catclrlevers H and M to set the same when adjusted.

O and 0 represent the adj ustingscgments; P and P, the plow-beams; Q, and Q, the moldboards; Q and Q, the landsides; R and R, the attaching-joints for the plow-beams; S, the plowshare, (shown in Figs. I and 5;) T and T, the sockets for locking the share and point to the mold-board bynicans of the key U.

V and V, and are designed for the bracing of the machine and hOlding the plows steady.

The following is the construction of my improved side-hill plow. I employ a central 5 bearing-wheel, A. to support the principal weight of the machine. Upon the axle of this wheel A, I attach the tongue B by means of the connectingbars D and D and E and E.

I connect the same with the bars F F and F F by means of the bar 0. I attach the seat- The through-brace screw-rods are marked supports G and G to the bars F F and F F, so as to form a conncctingbrace. To the seatsupports G and G, I attach the seat by means of the spring II. To the outer ends of the main axles I connect the adjusting guidewheels K and K by means of the levers Land L. To these levers I attach the catch-levers M and M to catch in the segment 0, into the holes of which they are forced and held by the springs N and N. I attach the plow-lift- 6o ing levers L and L to the plow-beams P and P above the plows. The catch-levers M and M catch in the perforations in the back part of the curved bars F and F, and are set fast and held by means of the springs N and N I form the mold-board and the landside in one piece and fit the share with a beveled edge to pass under the corresponding bevelededge of the mold-board and landside, and when the key U is passed through the sockets 73 T and T it thoroughly locks them together.

The following is the operation of my improved side-hill plow. The guide-wheels K and K are adjusted to the general grade of the hill by the driver, who operates the same 7 from his seat by means of the levers L and L, which are adjusted in the segment 0 by means of the catch'levers M and M and the springs N and N, and as the plow is turned to cut the next furrow the plow which has just completed its furrow is raised and the other plow let down by means of the plow-levers L and L the catclrlevers M" and M", and the springs N and N". The central bearing-wheel, A, supports the weight of the machine so balanced as to be'adjusted with but little effort, and the frame can be adjusted by the driver to any variation of the surface of the ground as the machine passes along.

The adjusting swivelrodsV and V are em- 0 p'loyed to tighten the bracing of the machine and prevent any lateral motion of the plow.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A sulky frame and axle, in combination with the adjusting guide-wheels K and K, the adjusting-levers L and L, for the purpose of adjusting the bearings of the machine or gang plow and maintaining the same in a vertical ICO position upon a side-hill or irregular surface, the plows, the adj usting-levers, the seat, and constructed and operated substantially as and the draft-tongue, constructed and operated for the purposes set forth. substantially as and for the purposes set forth. IO

' 2. The frame composed of the bars 0 D D 5 E E F F G G and the segment 0 and swivel Witnesses:

through-brace rods V and V, in combination A. STEWART, with the axle J, for the purpose of attaching J. B. PEPPIN.
